Experimental Study on Children Movement in a Stairwell of a Teaching Building

摘要

The purpose of this study is to investigate the movement characteristics of children in building stairs. In this study, four different experimental scenarios were conducted in a stairwell of a teaching building. The movement processes of children in the stairs were recorded by video cameras. The movement parameters of children in stairs were extracted and analyzed based on the recording data, including speed comparison between different scenarios, individual speed with respect to time and the fundamental diagrams. The results demonstrate that the gender and the movement type could influence the speed of children. The decreased trend of speed with the increase of density agrees with the results of adults, and the density of children on stairs in evacuation process could reach 6.4per/m~(2).
